Plural Runners Supported For Relative Motion Or On Separate Shafts Patents (Class 415/60)
  • Patent number: 4140433
    Abstract: A power-generating wind-driven turbine is disclosed which offers the advantage that it is compact and lightweight and is capable of producing a substantially greater output than a conventional windmill with a comparable size rotor. The turbine comprises an outer shroud and a nose cone which provide a streamlined wind collecting inlet designed so that the air stream is contracted to increase its velocity through the turbine blades, plus an exit section designed to exhaust the air stream with a minimum of turbulence.

  • Patent number: 4088419
    Abstract: An air operated power plant is provided with a pair of impellers rotating on vertical axes. A pair of panels is mounted in fixed relation to the impellers forming a V-shaped converging tunnel with the impellers near the rear of the V. The purpose of the tunnel is to act as an amplifier taking the wind from a large cross section and amplifying its speed and power and thereby concentrating its effect on the vanes of the impellers. The panels are built in the shape of vertical airfoils with the negative surfaces disposed outwardly so that wind which passes outside the structure will create a vacuum outside and behind the structure. The panels have openings behind the impellers so that the vacuum caused by the airfoil design forceably draws air compressed in the tunnel out past the impellers. The impellers and the entire power plant can be mounted to extend upwardly from the ground eliminating the need for a costly supporting tower. The impeller shafts can drive electric generators or any other desired load.

  • Patent number: 4037984
    Abstract: Pumps wherein smooth surfaced rotators cause propulsion of a delicate fluid without significant damage to the fluid. The pumps may be used as heart pumps, blood pumps, and pumps for all types of fluids in connection with the maintenance of life or biological functions in a human or animal subject in many in vivo, ex vivo, or in vitro applications, or for any other application requiring gentle fluid handling. The pumps may be actuated by internal or external electric motors, and the rotators may be configured to converge mutually as an inverse function of distance from the axis of the rotators. The rotators may be connected together, by pins passing through the fluid passages, for mounting and driving as a unit, or may be mounted and driven independently to further eliminate the possibility of damage to the fluid by rotator-connection members.

  • Patent number: 4025224
    Abstract: A multiple air motor drive unit in which the motors are mounted in series to permit the exhaust air from the first motor to be used in driving the second motor. The exhaust air from the second motor assists in driving the third motor. The exhaust air from the third motor assists in driving the fourth motor. A line extending from the intake side of the first motor provides additional air pressure to the intake side of each of the succeeding motors so that each motor is operating under the same operating pressure. The motors are geared to gears on a common shaft which extends through a universal joint to the apparatus to be driven.The unit may be used to help power a motor vehicle if desired.

  • Patent number: 4017204
    Abstract: Wind motors which are propelled by the impact of the wind against the vanes of an impeller wheel, that have wind channeling devices that gather the wind from a large area and funnel it at increased density and pressure to apply multiplied impact against the impeller vanes.
